user_enabled and user_enabled_emulation_dn not documented

[Matt Fischer]

The keystone configuration page lacks any documentation on these settings (http://docs.openstack.org/developer/keystone/configuration.html). I've spoken with Yorik (Yuriy) and given his bug and code comments I think I can get this documented.
